application filed forded for effecting a proper alignment of the j column after the bed-plate is secured to its foundation.

In the accompanying drawing, Figure l is a vertical section of the. lower portion of the column and base; Fig. 2, a plan View of Fig. l, and Figs. 3, 4, 5, 6, and 7, vertical sections illustrating modifications of my invention.

The column A, Figs. land 2, consists, in the present instance, of six segmental flanged bars, riveted together and constituting the well-known Phoenix column, for which Letv, ters Patent No. 35,582 were granted to S. J.

Reeves on the 17th day of June, 1862.

It should be understood, however, that my invention is applicable to any lrind of column, round, square,octagonal, or other shape.

B is the bed-plate, on which is cast asleeve or socket, b, for receiving the lower end of the column, to which the interior of the sleeve bears such relation that the column can be moved laterally in every direction in the sleeve toa limited extent.

The lowerl end of the column bears von the annular shoulder e of thefoot D, the upper portion of which iits snugly within the column, the lower portion being convex, and, as shown in Fig. 1, being adapted to a concave recess, f, in the bed-plate at the bottom of the sleeve. In other words, the column has a ball-and-socket bearing on the said bedplate.

The space between the column and interior of the sleeve is large enough for the proper alignment of the said column after the bed-plate has been firmly bolted to the foundation, and also for allowing for lthe subsequent fastening of the column in the sleeve by means of wedges, cements, or otherwise.

The most important result of my invention is j Jthe perfect axial bearing of the column, the whole lower end of which fits accurately to and must always bear uniformly on the portion cof the foot, even should the foundationplate be out of level.

My invention also permits the proper alignment of the column, after the bed-plate has been rmly bolted to the foundatiom without vinterfering with the accurate axial bearing of the said column. l

In the modification shown in Fig. 3, a

block, w, with upper concave surface adapted l to the convex under side of the foot, is interposed between the latter and the bed-plate,

in the bottom of the sleeve, the block being at liberty to move laterally to a limited ,extent, if necessary, for the proper adjustment of the column.

Inthe modication, Fig. 4, the under side of the foot D is concave, and adapted to a convex projection, m, cast on the bottom of the sleeve on the bed-plate.

In the modification, Fig. 5, the concave under side of thefoot bears on the convex upper surface of a block, n, contained within the sleeve.-

In order to insure the desired axial bearing of the column on the bed-plate under all circumstances, it is not essential that the foot should conform throughout to the bearing, as regards the concavity of one or the convexity of the other.

The under side of the foot may, for' instance, be very slightly concave, and bear on a comparatively abrupt central projection in the sleeve or on a block inV the Sleeve. (See Fig. 6.) The pointed or slightly rounded underside of the foot may rest in the slightly concave bottom of the sleeve, but IV prefer in all cases the ball-and-socket bearing shown in Fig. l, 3, 4, and 5.

I claim as my inventionl. The combination of a bed-plate and sleeve with a column, a foot on which has a In testimonyWl-lereof Ihave signed my name central bearing on the bottom of the said to this speoioation in the presence of tWo subsleeve,al1 substantially as specified. scribng Witnesses. v
